Force data were extracted from system logs for the Cadiere Forceps (static retraction) and Fenestrated Bipolar Forceps (dynamic retraction). Comparisons were made between three settings: Off (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u20093), Low (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u200911), and Medium (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u20095). For \"Low\" and \"Medium\" settings, cases overlapped as settings were adjusted intraoperatively. Cumulative force usage time was calculated for each setting. Statistical significance was assessed using the Kruskal\u2013Wallis test.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 91,000\u2009+\u2009seconds for Cadiere and 68,000\u2009+\u2009seconds for Fenestrated Bipolar forceps were analyzed. For the Cadiere Forceps (static retraction), the mean force was significantly reduced as FFb sensitivity increased (Off: 3.07 N, Low: 2.58 N, Medium: 2.03 N;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.039). For the Fenestrated Bipolar Forceps (dynamic retraction), while the mean force showed no significant difference, the median maximum (peak) force was significantly suppressed with higher FFb settings (Off: 36.19 N, Low: 18.82 N, Medium: 10.06 N;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.033).
